Cerebrolysin vs GHK-Cu (Copper Peptide)

A detailed comparison to help you understand the differences and choose the right peptide for your research goals.

Cerebrolysin

Cerebrolysin is a mixture of low-molecular-weight neuropeptides and free amino acids derived from purified pig brain proteins. It is approved in many countries for stroke, traumatic brain injury, and dementia.

Side-by-Side Comparison

Aspect	Cerebrolysin	GHK-Cu (Copper Peptide)
Dose Range	2150 mg–4300 mg	1 mg–2 mg
Frequency	1x daily	1x daily
Cycle Length	1–2 weeks	4–8 weeks
Route	intramuscular	subcutaneous
Mechanism	Contains multiple neurotrophic factors that promote neuroplasticity, reduce neuronal apoptosis, and support synaptic function. Has both neurotrophic and neuroprotective properties.	Attracts immune cells and fibroblasts to wound sites, stimulates collagen and glycosaminoglycan synthesis, promotes angiogenesis, and has antioxidant effects. Modulates gene expression related to tissue repair.
Typical Dosage	Clinical dosing: 10-30ml IV daily for acute conditions. Research use: 5-10ml IM daily for cognitive enhancement. Treatment courses typically last 10-20 days.	Topical: Applied as serum or cream 1-2 times daily. Injectable: 1-2mg daily for research purposes. Microneedling protocols often use 0.5-1%.
Administration	Administered via intramuscular or intravenous injection. IV administration is typically used in clinical settings. IM can be used for research purposes.	Most commonly used topically for skin applications. Can be injected subcutaneously for systemic effects. Often combined with microneedling for enhanced skin penetration.
Side Effects	Generally well-tolerated. May cause dizziness, headache, sweating, or injection site reactions. Rare cases of agitation or confusion.	Topical use is generally well-tolerated. May cause temporary skin irritation or redness in sensitive individuals. Injectable use may cause injection site reactions.
